The SUS316 cold-rolled stainless steel plate, adhering to the strict standards of JIS G4305, is a premium material renowned for its exceptional corrosion resistance, mechanical properties, and versatility in various industries. This article delves into the detailed chemical composition, mechanical properties, heat treatment state, available production dimensions, low-temperature impact testing, primary application scenarios, and specific supply cases by TJC Steel Group.

Chemical Composition

The SUS316 cold-rolled stainless steel plate boasts a well-balanced chemical composition that contributes to its exceptional performance. It comprises approximately 16-18% chromium (Cr), 10-14% nickel (Ni), and 2-3% molybdenum (Mo), along with trace amounts of carbon (C), silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S). The addition of molybdenum significantly enhances the material's resistance to chloride-ion stress corrosion cracking, making it suitable for harsh environments.

Mechanical Properties

In its cold-rolled form, SUS316 stainless steel plate demonstrates impressive mechanical properties. It exhibits high tensile strength, exceeding 520 MPa, and a yield strength of at least 205 MPa. The material also maintains excellent elongation, typically above 40%, ensuring ductility and formability. The hardness, typically measured in HBW, is dependent on the heat treatment process but remains suitable for various applications requiring high strength and resilience.

Heat Treatment State

SUS316 cold-rolled stainless steel plates undergo rigorous heat treatment to achieve optimal properties. The most common heat treatment state is the solution-annealed condition, which ensures a homogeneous microstructure and maximum corrosion resistance. This treatment involves heating the material to a temperature above its critical point, holding it for a specified time, and then rapidly cooling it to room temperature. The resulting microstructure is free from internal stresses and is characterized by its non-magnetic nature.

Available Production Dimensions

TJC Steel Group offers SUS316 cold-rolled stainless steel plates in a wide range of dimensions to cater to diverse customer requirements. The thickness can vary from 0.3 mm to 3.0 mm, while the width is available in standard sizes such as 1000 mm, 1219 mm, 1500 mm, and custom widths upon request. The lengths are typically 2000 mm or longer, with the capability to cut to specific lengths as per customer specifications.

Low-Temperature Impact Testing

SUS316 stainless steel, being an austenitic steel, exhibits good toughness even at low temperatures. However, to ensure its suitability for critical applications in extreme cold environments, low-temperature impact testing is performed. This test involves exposing standardized specimens to sub-zero temperatures and subjecting them to impact loads to assess their ductility and resistance to cracking. SUS316 consistently demonstrates excellent low-temperature toughness, making it reliable for use in cold climates and cryogenic applications.

Primary Application Scenarios

SUS316 cold-rolled stainless steel plates find extensive applications across various industries due to their superior corrosion resistance and mechanical properties. Key application areas include:

· Marine Environments: As a "marine-grade" stainless steel, SUS316 is widely used in seawater equipment, shipbuilding, and offshore structures due to its exceptional resistance to chloride corrosion.

· Food Processing: Its non-toxic and corrosion-resistant nature makes SUS316 ideal for food processing equipment, kitchenware, and surgical instruments, ensuring hygiene and safety.

· Chemical Industry: The material's ability to withstand aggressive chemicals and acids makes it suitable for chemical processing equipment, tanks, and piping systems.

· Architectural Applications: Its aesthetic appeal, durability, and resistance to weathering make SUS316 a popular choice for exterior cladding, roofing, and decorative structures.
